Frequently asked questions

Absolutely - fabric ducts are engineered for cleanliness, easy maintenance, and certified safety, ensuring a healthier indoor environment than many rigid systems. More information.

Generally yes - especially on larger projects. While price varies by location and system complexity, fabric duct systems often deliver substantial savings in both material and installation costs. More information.

Yes – fabric duct systems are inherently modular and designed for straightforward adjustments or extensions during commissioning and beyond. More information.

Yes – each modular section of a fabric duct carries its own unique identification tag, making spare-part ordering fast and accurate. More information.

Yes – Prihoda fabric ducts can be customized to interface seamlessly with any fire damper configuration, preserving fire-rated barriers and system integrity.
More information.

Not generally recommended – but possible in specific scenarios with proper material selection and installation safeguards. More information.

Yes – you can clean fabric ducts for hygiene, maintenance, or aesthetic reasons using straightforward procedures. More information.

Absolutely – CFD (Computational Fluid Dynamics) modeling is a core Prihoda service, allowing precise prediction of airflow patterns, temperatures, and velocities for any fabric diffuser design. More information.

Yes – from simple logos and solid colors to complex custom patterns, our Prihoda Art printing service delivers high-quality, durable graphics on fabric ducts. More information.

Yes – fabric ducts can deliver cold air below the dew point without condensation, thanks to permeable materials and engineered micro-perforations. More information.

Yes – fabric ducts handle warm-air distribution effectively when you account for air buoyancy and design the system accordingly. More information.

Insulated fabric ducts are available – fabric systems cannot be insulated using traditional wraps but are constructed with integrated insulation during manufacturing. More information.

Yes – fabric ducts are available in numerous profiles to suit architectural and functional requirements, from traditional rounds to bespoke multi-lobed configurations. More information.

Yes – Prihoda’s custom-fabricated ducts can navigate any angle or directional change with precision. More information.

Not generally – fabric systems self-balance in closed installations, though dampers are recommended in mixed or open configurations. More information.

Generally, you don’t need extensive commissioning – Prihoda fabric duct systems largely self-balance when correctly connected and specified. More information.

Yes – fabric ducting systems can be installed in different ways, depending on the shape of the duct and the structure you‘re attaching it to. More information.

Fabric ducting can significantly improve indoor air quality (IAQ) – primarily by delivering air more evenly, gently and hygienically. With more active diffuser surface in the space, air is distributed efficiently to all areas, creating a healthier and more comfortable environment. More information.

Typical operating pressure for fabric ducting ranges from 40 Pa to 400 Pa, with most systems working around 120 Pa. The exact pressure required depends on your specific application – especially the mounting height, type of air being supplied, and what the system is designed to do. More information.

Noise from a fabric ducting system can depend on both subjective perception and measurable acoustic criteria. At Prihoda, we take both into account when designing any system. More information.

Yes – fabric ducting is highly suitable for displacement ventilation and often provides a more flexible and efficient solution than traditional diffusers. More information.

Most Prihoda fabric ducting materials are flame retardant, but it’s important to distinguish between flame retardant and non-combustible materials. More information.

Fabric ducting offers a wide range of benefits – from faster installation to improved air distribution. While many advantages depend on the specific project, one key benefit stands out above the rest. More information.

Possible limitations of fabric ducting depend on the specific application. While fabric ducts offer many advantages, there are certain situations where they may not be the ideal solution. More information.

It depends on the shape of the duct and how it’s supported. When airflow stops, fabric ducts lose internal pressure and may deflate – how they behave in this state is determined by their design and suspension method. More information.

The embodied energy of Prihoda’s standard NMI polyester fabric is calculated as 16.56 MJ/m². This makes fabric ducting a significantly lower-impact option compared to traditional materials such as sheet steel. More information.

The ideal air velocity inside a fabric duct depends on the project type and available pressure in the system. However, as a general design guideline, it‘s best to keep velocity below 8.0 m/s to balance performance, comfort, and energy efficiency. More information.

A well-installed and properly maintained fabric ducting system can last more than 25 years. Many Prihoda systems installed in the 1990s are still in operation today. More information.

It depends on the application, but in general, fabric ducts can be installed at heights of up to 20 metres – and sometimes even higher, depending on airflow conditions and system design. More information.

Fabric ducting systems can be designed to run over 200 metres (650 feet) – depending on the available fan pressure and the airflow requirements of the project. More information.
